Provided is a pneumatic tire which comprises, as a skeleton, a carcass 2 extending toroidally between a pair of bead cores 1 individually embedded in a left-and-right pair of bead portions, and is provided with an oblique steel belt layer 3 which is arranged on the periphery side of a crown portion of the carcass 2 and in which a plurality of cords extending obliquely with respect to the tire circumferential direction are arrayed, and a circumferential direction belt layer 4 which is arranged on the periphery side of the oblique steel belt layer 3 and in which a plurality of cords are arrayed substantially in parallel with the tire circumferential direction. The cords 5 of the oblique steel belt layer 3 are placed side by side in a belt width direction in a unit of a bundle of a plurality of parallel steel filaments and the cords 6 of the circumferential steel belt layer 4 are placed side by side in a belt width direction in a plurality of twisted filaments.",
